- 7 ill-aims. (Cl. 105-234) The invention relatesto railway rolling stock and consists in a novel construction of a locomotive tender underframeand stoker trough with associated parts;

The main objects of the invention are to provide a rigid stoker trough, to'mo'unt the same securely upon the tender underframe; and to providea water-compartment at ,the sides of and below the trough. but avoidingvthe' contact of water with the troughwalls. a

Another object of the invention is to provide adequate compartments for the stoker driving mechanism including preferably a compartment for the stoker enginemounted on the tender.

Another object of the invention is to simplify the assembling of the associated parts of the structure andthe elimination of rivets and bolts to a greatextent thereby avoiding considerable tendency to leaks and other deterioration in the structure.

In the accompanying drawings illustrating the invention- 1 Figure l is a top view of a stoker trough casting with associated underframe, tank walls,

and other parts indicated in dot and dash lines.

Figure 2 isa side elevation of the trough.

, Figure 3 is a longitudinal vertical section taken onthe center line of the trough and underframe as indicated at 33 in Figure 1.

Figure 4 is a front elevation of the trough with associated parts indicated in dot and dash lines, 1 Figure 5 is a corresponding rear elevation.

Figures 6, '7 and 9 are vertical transverse sec tions taken on the corresponding section lines of Figure 1. i v v Figure 8 is a detail longitudinal sectiontaken on the line 88 of Figure 1.

Figure 10 corresponds to Figure 6 but illustrates a modification of the invention. Figures 11, 12 and 13 correspond to Figures 1, 2 and 3 but illustrate a modified form of the invention.

Figures 1 to 9, inclusive, a stoker trough l is formed of a one-piece casting including lateral flanges 2 and 3 projecting outwardly from the frame, to the trough, and to each other;

upper portions of the side walls and also including depending feet 4; 5, 6,. and l whereby the trough is supported in a position spacedabove the tender under frame upon which it is mounted.

The underframe is of the water bottom,type 5 including a horizontally disposed bottom web 8, center sills 9, side sills ii], transverse transoms it, an end sill i2, andacenter plate l3. JIhe "underframe preferably comprises a single casting forming thebottom of the tender tank and util- O izing the depth of the underirame as part of the Water storage tank as disclosed in Ashe & Pflager Patent #l,663,036. Tender side platesi i are secured tothe underframe side sills H] by welding or riveting. I f

Throughout a substantial portion of itslength the trough casting includes a horizontal web '15 (Figure 6) projecting outwardly from'the lower portion of the troughto points below the outer edges of flanges 2 and 3. Plates it are secured to the outer portions of flanges 2 and 3 and web l 5 andextendupwardly from the trough to form e Cl walls of the water compartment of the tender.

At the forward portion of the troughlweb 15 turns downwardly,'a's indicated at I! (Figure 9),

to be secured to a horizontal web 58 provided-on the underframe casting and forming the. top Wall of a water chamber in the underirame and the bottom wall of a' compartment 59 (Figure 7) for housing the stoker engine Zii. This engine compartment is completed by theplates 2t, 22, 23, 24 and M which are secured to the under- 7 The space between the trough and plate 22 and plate it on the right-hand side of the trough forms a closed compartment 25 for the conveyordrive sh a1t 26 journaledin bearings formed by brackets 2] extending between the body of the trough and weblii r I Figure 8 illustrates the mounting and drive 4 connection for the rear portion of the drive a shaft 25. One of the bearings Z'lis spaced inwardly from the rear end of the device and the rear Wall 29 is provided with an integral bearing 28 and a rearwardly opening housing 2% for the gear 33a attached to stub shaft 36. The adjacent ends of shafts 26 and 38 are squared and a connecting collar 35 couples these shafts together.

Figure 18 illustrates a modified arrangement utilizing a single bearing and housing member '38 integral with the trough side wall and provided with a renewable bushing 49 in which the collar 5t rotates. This arrangement facilitates the removal of the shaft portion 5| and thegear 52 mounted thereon without necessitating access to the interior of the chamber in which the forward shaft portion 531s mounted. This avoids any diiiiculty which might be experienced in connecting the ends of the shafts usually located intermediate of spaced bearings and also facilitates the renewal of the rear bushing since this is readily accessible. I

Figure 10 illustrates a. modified structure in which a horizontal web 33 of the trough casting is spaced a substantial distance below the trough 34 and extends directly between the upper flanges of the underframe center sills 35. This arrangement decreases the water capacity somewhat but provides a wider base for the trough casting and an, increased mechanism compartment.

In the modification illustrated in the remaining figures, the portion of the underframe beneath the trough 36 includes upward extensions 3'! or" the center sills 38 and upward extensions 45 of the transoms 45 and a horizontal web'39 adjacent tothebotto'm of the trough, The tank plates! are secured to the flanges 4i of the trough and to the upper portions or the extensions 3'5 and 45. This construction provides the underframe with an upwardly extending" water compartment 42, the top and side walls of which are integral with the remainder of the under--v frame casting. The trough casting is provided with pairs of laterally spaced feet 43 resting on pads 44 on the horizontal web 39 and is substantially lighter than the troughs previously described;

, Various other modifications in the details of the construction may be made without departing from-the spirit of the invention and exclusive use of all structures coming within the scope of the appended claims is contemplated.

What is claimed is: 7 1. In a locomotive tender, an underframe, a stoker trough, depending elements on said trough supporting it on and in an elevated position above said underirame, and tank wall elements spaced from the side-s of the trough and extending from the level of the upper edges of said trough downwardly and beneath the same and above said underirame to form walls of a water compartment at the sides of said trough and extending beneath the latter above the top of said underirame.

2; In a locomotive tender, a water bottom underframeincluding vertical longitudinal sills and vertical transverse members, a stoker trough having depending'feet mounted on certain of said members, aweb disposed substantially horizontally intermediate said trough andmembers, and tank wall plates extending from said web upwardly and secured to the sides of said trough,

said web forming an upper wall for a portion of a partment extending above said sills and beneath andspace d from'said trough.

4. In a locomotive tender, an underframe having longitudinal center sills and transverse transoms; upward extensions on portions of said sills and transoms, a horizontal web joining the upper edges of said extensions and forming therewith the top and side walls of awater receiving compartment extending above said sills and transom's, a stoker trough above said compartment and spaced from the walls thereof, and tender tank plates connected to said walls and extending upwardly at the sides of said trough.

5. A stoker device casting comprising a V- V shaped trough body and a horizontal web beneath the same to provide the top wall of a water compartment below the stoker device, and

relatively narrow supporting feet projecting downwardly from the central portion of said body and web for mounting the casting on an underframe;

6.
